As Oil Reaches $111 a Barrel, Are Gas Price Spikes Next?

The price of oil does not pass through to gas prices directly because of the sources of the crude and refinery and transportation costs. However, it does pass through eventually.

Gasoline prices in the United States continue to run well below those of a year ago. The cost of an average gallon of regular nationwide stands at $3.542, compared with $3.75 on the same day in 2012. As some historical evidence the figure could go much higher very quickly, prices have spiked sharply three times in the past two years, and approached $4 in March and April of 2012.

The discussion of a rapid run up in gas prices quickly comes around to U.S. gross domestic product. Economists have not built a consensus model about what a penny increase does to consumer spending, or to the margins of companies that use oil-based fuels or petrochemicals.

The swiftest reaction among public companies is usually from airlines, an industry in which jet fuel prices may determine the difference between profit and loss. Passenger carrier shares have sold off sharply in the past two days, a trend that likely will continue if oil’s advance does.

At the core of the analysis of gas prices and their effect is consumer reaction. Often this analysis is done based on households with four people. The mid-point of the analysis often starts with national median household income ,which is about $51,000 but actually has dropped in real dollars in the past decade. The logic for the damage done by higher gas prices is usually the same. The lower middle class and those closer to the poverty line have to curb discretionary spending, to the extent that they have any discretion at all.

Gasoline prices will go up, and soon. With that, the guessing game on injury to economic growth will be stirred up again.
